RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 681,469, dated August27, 1901.

Application led April 16, 1901.

To @ZZ whom it may concern.-

Be it known that 1, CHAELEs H. WILSON, a citizen of the United States,residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Railway-Switches,of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to improvements in railway-switches, andparticularly in that class of railway-switches which are adapted to beactuated by depressible mechanism mounted adjacent to the railway.

One object of the invention is to provide a simple and compactswitch-actuating mechanism.

Another object of the invention is to provide a switch-actuatingmechanism which shall be positive in its operation.`

The further object of the invention is to improve the generalconstruction of the switch.

The invention also consists in such novel features of construction andcombination of parts as shall hereinafter be more fully described, andpointed out in the claim.

In the drawings, Figure 1 represents a plan view of a railway providedwith the improved switch. Fig. 2 represents a side elevation, partiallyin section, of portions of the same. Fig. 3 represents a perspectiveview of portions of the same to more clearly show the construction andrelation of the parts.

Similar numbers of reference designate corresponding parts throughout.

In carrying this invention into practice I construct a bed-plate 5,having the grooves 6 6 and 7 7 with the frogs 8 and 9 and provided withthe pivoted tongue 10, forming a swinging extension of the frog 9. Inthe bottom of this bed-plate 5 is formed the lateral slot 11, andthrough the thickness of the bedplate are formed parallel openings 12and 13, which have the inclined exits 14 and 15 and are also parallel tothe grooves 6 6. Beneath the bed-plate 5 and mounted to move laterallyon any usual supports, as the plates 16 16, is the switch-tongueactuator 17, pivotally connected with the switch-tongue 10, having theportion 18,7considerably less in height than the main portion, which isfurnished with the inclined or cam end 19 and Serial No. 56,076. (Nomodel.)

with the lateral projection 20, having the inclined cam-face 2l. 13 arepivoted the plates 22 and 23, each having aweighted arm 24 or 25, theplate 22 having the depending cam 26, the inclined face of which bearsagainst the face of the cam 20. The free ends of the plates 22 and 23are depressible until their lower surfaces strike the steps, as 28, atwhich time the upper surfaces of these plates are brought opposite thesurfaces of the exits 14 and 15. Means 4are provided on the cars whichmay be brought against either of the plates 22 or 23 to depress the sameas the car approaches the switch. The depressing of the free end of theplate 22 causes the inclined face of the cam 26 to work against the faceof the cam 19, thus forcing the actuator 17 and the free end of theswitch-ton gue toward the rail 7, while the depressing of the free endof the plate 23 causes the cam 27 to work against the cam 2O to move theactuator 17 in the opposite direction and to cause the seating of theend of the tongue 10 against the rail 6, the mechanism which bearsagainst the plates 22 or 23 passing out from between the walls of theopenings 12 and 13 by means of the inclined exits 14 or 15 and theweighted arms 24 or 25 of the plates then causing the raising of theplates to the plane of the bed 5.

It is of course obvious that any usual depressing means may be used todepress the plates 22 or 23 and that the proportions of these platesmust depend somewhat upon the nature and size of this depressing meansas also of the precision of its operation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination with the bed-plate 5 having theopenings 12 and 13, and the plates 22 and 23 pivoted in such openingsand having the arms 24 and 25 and the cams 26 and 27, of the actuatormounted to move laterally beneath such bed-plate and having the cam 19and the extension 2O with its cam-face 2l, as and for the purposedescribed.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES II. WILSON.
